LIGHTING (EXT) LIGHTING SYSTEM(w/ Headlight ECU) Clearance Light/Daytime Running Light Circuit

DESCRIPTION

Clearance light function:

When the main body ECU (multiplex network body ECU) receives the light control switch position signal, it sends an illumination request signal to the headlight ECU sub-assembly LH/RH and illuminates the clearance lights.

Daytime running light function:

When the operation conditions of the daytime running lights are met, the main body ECU (multiplex network body ECU) sends an illumination request signal to the headlight ECU sub-assembly LH/RH and illuminates the daytime running lights.

CAUTION / NOTICE / HINT

NOTICE:: ·

If the headlight ECU sub-assembly LH has been replaced, it is necessary to synchronize the vehicle information and initialize the headlight ECU sub-assembly LH.
